ADJUSTING MECHANISM FOR LAMPS FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Oct. 10, 1911.

Application filed May 5, 1911. Serial No. 625,138. a

To all whom it may concern:

Be it known that I, ARTHUR JAMES FAR BELL, a citizen of the UnitedStates of America, residing at Pittsburgh, in' the county of- Alleghenyand State of Pennsylvania, have invented certain new and usefulImprovements in Adjusting Mechanism for Lamps for Automobiles, of whichthe following 1s a specification, reference being had therein to theaccompanying drawing.

This invention relates to an adjusting mechanism for the lamps forautomobiles and other vehicles, and the object of my invention is theprovision of positive [and reliable means in a manner as will behereinafter set forth, whereby the lamps of an automobile can beadjusted simultaneously with the forward wheels of the vehicle toillumine the path in the direction in which the wheels are steered.

I attain the above object by a mechanical construction that isapplicable to the present type of automobiles, the mechanism beingsimple in construction, capable of withstanding the jarring and bumpingto whlch it, is subjected, and highly eflicient as a safety factor forthe occupants of the vehicle and pedestrians in the vicinity of thesame.

The invention will be hereinafter specifically described and thenclaimed, and reference will now-be'had to the drawing where- 1n Figure 1is a side elevation of the adjusting mechanism, and Fig. 2 is a plan ofthe same partly broken away and partly in section.

The reference numeral 1 denotes the side frames of an automobile, theseframes adjacent to the forward ends thereof having inwardly projectingbearings 2. Rotatably mounted in the bearings 2 are vertical shafts 3,said shafts being retained within the bearings by washers 4 mounted uponsaid shafts above and below said bearings. The upper ends of the shafts3 are provided with lamp holders 5 for lamps 6, and mounted upon 7 saidshafts, adjacent to the holders, are rearwardly extending cranks 7having the rear ends thereof pivotally connected by pins 8 to aconnecting bar 9. The cranks 7 have sleeves 10 to receive the shafts 3and these sleeves are clamped to the shafts by set screws 11.

Mounted upon the lower ends of the shafts 3 are horizontal beveled gearwheels 12 meshing with beveled gear wheels 13 mounted upon the forwardends of shafts 14, journaled in hangers 15, carried by the frames 1. Therear ends of the shafts 14 have beveled gear wheels 16 meshing withsimilar gear wheels 17 mounted upon the transverse shaft 18, journaledin hangers 19, carried by the frames 1. The shaft 18 is provided with agear wheel 20 and meshing with this gear wheel is a worm 21 upon thelower end of the steering post .22 of the automobile. .The steering postis of the ordinary and well known type and has suitable connections forsteering the forward wheels 23 of the automobile. When the post 22 isrotated a similar movement is imparted to the shafts l8 and 14, andthrough the medium of the beveled gear wheels the vertical lampsupporting shafts 3 are shifted, these shafts moving in unisoncthroughthe medium of the connecting bar- 9.

What I claim is In a lamp adjusting mechanism for vehicles provided witha steering gear, a worm on the post of the steering gear, two verticallamp supporting shafts journaled in bearings carried by the side framesof the vehicle, a beveled pinion on the lower ends of each shaft, a pairof horizontally-extending shafts journaled in hangers carried by saidside frames, beveled pinions on the forward ends of said shaft andmeshing with the pinions on the lower ends of the verticalshafts,beveled pinions on the rear ends of said shafts, atransversely-extending shaft journaled in hangers carried by said sideframes and,provided with beveled pinions meshing with the pinions on therear ends of the horizontally-extending shafts, a worm wheel on saidtransverse shaft meshing with the worm on the steering post,rea'rwardlyextending cranks carried by said vertical shafts, and aconnecting bar pivotally attached at its ends to said cranks.

In testimony whereof I aflixmy signature Witnesses:
